摘　　要：目前嵌入式操作系统在信息化进程中扮演着越来越重要的角色,被广泛应用于各行各业。对于嵌入式实时操作系统,多任务间数据通信是影响系统功能和性能的关键因素之一。当前多数的实时系统内核中所提供的任务间通信机制在一对多、多对一的任务间通信中效率不高,实时性不强。为此,本文提出了一种基于SylixOS的多任务间数据通信的方法,这种方法的特点是将传统的信号量机制配合消息环形队列的使用可以大大提高任务间通信的效率,实时性强。为复杂多核嵌入式系统多任务间数据通信工程实现提供了重要参考。At present,embedded operating system plays a more and more important role in the information process and is widely used in all walks of life.For the embedded real-time operating system,data communication between multiple tasks is one of the key factors affecting system function and performance.At present,the inter-task communication mechanism provided in most real-time system kernel is not efficient and real-time in one-to-many or many-to-one intertask communication.For this reason,this paper proposes a method of inter-task data communication based on SylixOS.This method is characterized by the use of traditional semaphore mechanism combined with message ring queue,which can greatly improve the efficiency and real-time performance of inter-task communication.It provides an important reference for the implementation of multi-task data communication engineering in complex multi-core embedded system.
